OK, so this, what I've sketched here would be a constant pressure calorimeter. There's a reaction.

好，我画的就是一个恒压量热计,其中进行一个反应。

Could be done, but easier is to just do the whole thing at constant volume, right, and just run the reaction that way and redo the calculation to be a constant volume rather than constant pressure calorimeter, right.

可以进行测量,但是如果在体积恒定的条件下,做这些会容易得多,还是这样进行反应,但是在等体而不是恒压条件下重新计算。
